Does anyone know of a replacement seal that would work, without buying the whole pump?

If it is like my 29 L (which has the flat belt) there is a packing nut that can be tightened or take the nut off and install some graphite rope and tighten (don't make it too tight though)

Don't know if it will help but, years ago I bought a "kit' for my LA from Case dealer. Had a seal. I was told to not have the impeller tight to the shaft. It was on a pin and needed to move to align against the seal.

My L (1937) doesn't have a seal, that I recall. I had the pump out about six years ago. The shaft runs through a long bushing, probably bronze, that is a close fit, and the grease is all that keeps it from leaking. Apparently the hydrodynamics keep it from leaking when the engine is running, and when I shut it off, I just turn the grease cup down enough to fill the space between the bushing and shaft. It helps to turn the fan while screwing down the grease cup, to distribute the grease. If I do this, leakage while not running is negligible.

If I reccolect the "seal" is a metal cap that runs against the wall of the pump casting. There is no seal in the conventional sense. I don't remember having a problem with them leaking either.
